Did you know that the average person on earth used 350 litres of water a day. That’s over 1400 cups of water. Water consumption is critical on Earth but even more so here on the International Space Station where we have a closed environment. From washing ourselves to, from making our coffee, even when we sweat, the water that gest expelled is collected into a purification system and we reclaim about 93% of all the water on board. Definite soapy water here on space. Mix it up. Got some on the outside apparently.

Water used to be delivered in water-filled bags like this one. We brought them up on space shuttles and of course all of the revisiting re-supply vehicles. But since, 2010, we have a system on board, that can purify the water real-time, you don’t have to take it out and store it in bags.

We have filters and a keg sized distiller that spins to create artificial gravity and move the waste water along and with it we can recycle about 6,000 litres of extra water for the station each year. We even recycle our urine. (Ewwwwwwwww) But before you cringe at the thought of drinking your left over wash water and your leftover urine.

Keep in mind, that the water we end up with is purer than most of the water that you drink on a daily basis at home. That makes the International Space Station it’s own self-contained environment. That’s the critical step towards living for long periods off of planet Earth.
